Description

Technical Field

[0001] The invention relates to the field of intelligent control technology, and in particular to an intelligent control system for a precision coating and curing process of an industrial filter paper production line. Background Art

[0002] Intelligent control is a technical field that uses computers and other electronic devices to automatically make decisions, with the goal of mimicking or enhancing human control capabilities. It is mainly used in industrial automation, robotics, transportation systems, energy management, and many other areas. Intelligent control systems usually include sensors that perceive the environment, actuators that perform operations, and decision algorithms. The decision algorithms may be based on classical control theory, artificial intelligence, or hybrid methods, aiming to improve efficiency, accuracy, and responsiveness while reducing the need and complexity of human intervention.

[0003] Among them, the intelligent control system for precision coating and curing process of industrial filter paper production line is a specific intelligent control system belonging to the industrial manufacturing process. The system is mainly used to control and optimize the coating and curing process on the industrial filter paper production line to ensure production efficiency and product quality. Precision coating and curing is a process that involves uniformly coating a specific chemical or physical material on the surface of the filter paper and curing it. This process has extremely high requirements for the uniformity, thickness and degree of curing of the coating. The intelligent control system ensures that each step is precisely controlled by real-time monitoring and adjustment of equipment parameters to achieve the best production effect and product performance.

[0004] Existing intelligent control systems for industrial filter paper coating and curing usually lack the necessary flexibility and precision, and often perform poorly in real-time response to production line changes, coating precision control, and environmental parameter adjustment. Traditional technologies fail to accurately control the position of the die or adapt to environmental fluctuations during the coating process, resulting in unstable product quality, increased production costs, and waste of resources. In particular, in terms of environmental control, the failure to monitor or adjust microenvironmental conditions in detail, such as changes in temperature and humidity, is crucial to precision manufacturing, because even minor environmental changes may have a significant impact on the performance of the final product. These technical limitations not only reduce production efficiency, but may also lead to product rework and quality claims, increasing the company's operating costs and market competition pressure.

[0021] Suppose there are three sample concentration data: .

[0022] First calculate the average concentration : Now, insert the formula to calculate : Mixing uniformity percentage The concentration deviation of the samples is an average of 6.67% of the original average concentration, demonstrating how evenly the coating materials are mixed.

[0023] Assumptions mg / L, (obtained from the previous calculation), .

[0024] Substituting into the formula, we get: New active ingredient concentrations mg / L means that based on the difference between the current mixing uniformity and the target uniformity, the original concentration is reduced by the sensitivity adjustment factor in an attempt to achieve a more uniform mixing state.

[0025] Assumptions mg / L, mg / L (obtained from the above calculation).

[0026] Substituting into the formula, we get: Formula compliance rate It means that the adjusted formula concentration is very close to the target formula concentration, reaching 97.5% consistency, which shows that the formula adjustment is effective in approaching the target formula requirements.

[0030] Assumptions L / min, (The reaction rate slows down slightly as the temperature decreases), K, K.

[0031] Substituting into the formula, we get: New reaction rate L / min indicates a slight increase in reaction rate due to a small decrease in temperature, probably because some chemical reactions are more efficient at slightly lower temperatures.

[0032] Assumptions L / min, L / min, L / min.

[0033] Substituting into the formula, we get: New flow rate L / min means that the flow rate is fine-tuned accordingly to the slight increase in reaction rate, ensuring that the discharge matches the reaction rate to avoid waste of output or resources.

[0044] Continue to use ,but: Assumptions ,but: New speed Units / second, indicating the speed that needs to be increased to cope with position deviation.

[0045] New track offset -0.88 means the applicator head should be adjusted approximately 0.88 units to the left to align with the filter paper.

[0046] Assume the current position of the coating head is 200.

[0047] Substituting into the formula, we get: Optimized coating position This indicates that the position of the coater head has been adjusted to the left by approximately 0.88 units, which will allow the coating to be more accurately aligned with the filter paper.
